2014-6-1  Unlike in the dry mill, where ball impact velocity is the same for all the ball sizes, the impact velocity in a wet mill increases as the ball size increases. It is easy to understand that the liner life is considerably shorter with large balls than with smaller balls, since the impact impulse increases exponentially as ball size increases.

Effects of percent solids and mill loading on ball wear

The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44-µm (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp
